I got some problem with this. I changed from my earlier 10 mm spacers to 5 mm. These thin spacer didn't have any hub and I have to center them in someway. I had they mounted earlier and then I center them direct with my fingers, the wheel was centered with the ordinary hub ring.

But now when I have my 3D-printer, why not made the hub rings that fit perfect by myselfe ?

Have a look at page three:
2005 years Chrysler Crossfire: Hub center rings, part 1

But better to buy new ones, I just was curious and wanted to do some test.
